我安装了 JBoss AS 7.1.1 服务器。我创建了我的项目战争文件并将其放在 [JBOSS_HOME]\standalone\deployments文件夹下。
我的应用程序是 Spring MVC，这是我的 web.xml

在控制台日志中，myapp-servlet.xml 由 spring 加载，所有请求映射都是从我的控制器完成的。部分日志输出：
12:27:13,440 INFO [org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping] (MSC service thread 1-4) Mapped URL path [/myapp/welcome] onto handler 'myappController'
12:27:13,442 INFO [org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping] (MSC service thread 1-4) Mapped URL path [/myapp/welcome.*] onto handler 'myappController'

12:27:13,565 INFO [org.jboss.as] (MSC service thread 1-1) JBAS015951: Admin console listening on http://127.0.0.1:9990
我的控制器类很简单：
@Controller
@RequestMapping("/myapp")
public class MyappController {
private static Logger log = Logger.getLogger(MyappController.class);
// @formatter:off
/**
* Welcome to MyApp
*
*
* @return welcome.jsp Page
*
*
*/
// @formatter:on
@RequestMapping(value = "/welcome", method = RequestMethod.GET)
public String welcome() {
log.debug("welcome() called...");
return "welcome";
}
}
如果我访问http://localhost:8080/，那么我的welcome.jsp 会加载到网页中。
但问题是现在当我尝试使用以下网址访问时，我http://localhost:8080/myapp/welcome.jsp在网页中看到此错误：
HTTP Status 404 - /myapp/welcome.jsp
--------------------------------------------------------------------------------
type Status report
message /myapp/welcome.jsp
description The requested resource (/myapp/welcome.jsp) is not available.

这里有什么问题？
